Coliseum

Another excellent map from the author of ds1v3. This one is set in a symmetrical marble arena, with 4 different areas containing the weapons and keys. The appearance and architecture is good, as is the progression. The gameplay isn't quite as good, though. Few fights are fun, you get most of the goodies very late, and for 100% kills you have to snipe monsters far away. These are minor complaints, though. 4 official secrets, but it's just one, really (a switch opens all of them). Recommended. --4/5

This is dated April 1995. You get two versions of the map, one for Doom and one for Doom II. I played the second. It's a hub-style dungeon level, with a small central courtyard and four mini-arenas at the compass points. It's superficially fun although erratic; you get far more weapons than you need against weak oppo, a couple of traps seemed to not work, lots of stuck imps. And the mini-arenas are really just one room big. As a quick blast it's okay though.
